usb: chipidea: core: handle usb role switch in a common way

Currently, ci_usb_role_switch_set() may be called before system resume
stage when suspended. Worse yet, ci_hdrc device may stay at RPM_ACTIVE
state which will cause pm_runtime_get_sync() fail to resume the device.
In this case, role-switch may unable to complete transition process due
to not exit from lpm state or due to lack some means after system resume.

Same as ci_cable_notifier(), usb_role_switch could handle its events based
on ci_hdrc_cable mechanism.
